Infinity patented Ultrex windows can help to decrease your home’s energy costs by almost half. Test results show that the energy used to heat or cool your home can be lost through poorly insulated windows. Seattle and surrounding area homes with drafty windows often suffer from unnecessarily high bills. The combination of poorly fitted frames, inefficient glass and porous wood or vinyl frame materials combine to waste the money you spend to keep your home safe and comfortable.

Infinity replacement windows look like traditional wood, but are a longer lasting option compared to traditional wooden windows. The unique Ultrex® fiberglass technology makes these windows energy efficient and tough. Built on over 100 years of heritage from Marvin, Infinity windows remain weather tight even in extreme weather. The risk of air leakage is reduced due to the low thermal expansion rate of fiberglass. With a variety of premade types and sizes available, Infinity windows can also be customized to meet the needs of any space in your home. These windows incorporate the details of traditional wood windows without the maintenance, so you will be pleased that you made the right choice choosing Infinity from Signature Window and Door Replacement.

"We attended the Spring Home Show and looked into 3 different brands of windows. We did our research and were most impressed with Infinity from Marvin. Not only because of the window itself but also because they could match the oak floors, trim, and oak cabinets. Not only did they match it but it looks incredibly beautiful. We chose to add the bow window. It was perfect. Steve was a knowledgeable and sincere salesman. The service was incredible, the installers, more incredible. The team sent up here were meticulous about every fine detail of the installation and very thoughtful about our time, home and space. And...the windows are fantastic. Good investment. Highly recommend them over other name brands."
